Could be wrong, but AFAIK the CATL Sodium batteries haven't yet hit LFP pricing.

You are unlikely to see a vehicle with sodium batteries until after that happens, and it needs to be significantly less than LFPs as you Na batteries have more weight per Wh. I believe they also have a shorter lifespan (but not NMC short). Edit correction, looks like CATL is promising 15000 cycles, which is much longer than LFPs which usually come in at 7000 to 10000.

It seems far more likely to me that if the Na prices tank, you'll probably first see them deployed as grid and home battery solutions.

The energy density of LFP batteries are also 30-50% higher than sodium based battery chemistries. Even if sodium battery prices drop, the lower energy density is a big disadvantage. My understanding is that sodium batteries are aimed at stationary use-cases, like battery buffers for fast charging.

At the cell level yes. But at the pack level, you need less/no cooling and there is virtually no risk of runaway fires. This means the cells can be packed more densely and you get some weight benefits for all the stuff you no longer need for fire safety.

CATL already put sodium ion in cheap cars. And there are other benefits to this type of battery like a wider range of operating temperatures that cover essentially all of the extreme temperatures you'd find in the arctic and the hottest deserts.

I would not be surprised to find some of these batteries in big semis a few years down the line when the cost benefits make the space/weight sacrifices worth the trade off.

But you are right that domestic and grid storage are also going to be huge use cases.

For about a half of year there have been cars with sodium-ion batteries, in China. As you say, for now they are more expensive, but it is expected that the price will drop quickly in the following years.

Because they lose neither capacity nor charging speed at low temperatures, like the lithium-ion batteries, they expect that in the future sodium-batteries will be the best choice in the countries with cold climates.

One of the most interesting features of sodium batteries is that they still perform good in cold temperatures.

And high temperatures, too. Meaning they don't require cooling nor heating, basically matching the per kg capacity of ready modules with LFP while being significantly safer and less complex.

They're promising to start selling a Qiyuan A06 variant with Sodium batteries sometime this year... so if you went looking you could probably see one... or will be able to soon.

Looks ideal for a power wall at home.

Superior temperature range in cold weather as well IIRC.

Unlikely.

EESMs are primarily manufactured by European OEMs (ZF, MAHLE, Schaffler, AEM) and their Indian JV partners (Sona Comstar, Sterling, and the India branches of the OEMs listed). Both have been blocked via export controls from accessing battery tech from China over the past few years, and a major reason for the push for EESMs was for an ex-China supply chain, especially after China began export controlling rare earths to the EU [6].

Additonally, Chinese and American EVs tend to use PMSMs unlike European and now Indian EVs. Also, the EU is cracking down on automotive exports (cars and OEMs) from non-FTA states as part of the EU Industrial Accelerator Act (which btw has made China go ballistic [2][3][4][5]).

On the other hand, they will most likely use Japanese or Korean solid-state batteries as Idemetsu Kosan is in the process of mass producing them [0][1] as is LG [7], and both Japan+SK are FTA partners with the EU.
